Connection via Serial Cable

For some reasons it may be useful to connect via serial cable instead
of using a real infrared link. Bjorn Hanson wrote: "Using a cable, I
managed to get a PPP connection through my Ericsson SH888. I did the
following (maybe some steps are wrong but they worked for me :-)

added alias tty-ldisc-11 irtty to
/etc/conf.modules

edited /etc/irda/drivers to irattach /dev/ttyS0

manually inserted the irda and irtty modules using modprobe

start irattach

run kppp using /dev/ircomm0 (through symlink /dev/modem)

executed stty < /dev/ircomm0

ping the host

ifconfig irda0 down

Everything worked fine for ping and ssh (doing ls -l a couple of
times) but the computer hang when I tried to mail (Netscape) this
through that PPP. After reboot I tried both Netscape and lynx. Both
were able to establish contact but none got any data."

Please note this is not the recommended way to connect two machines.
Use PPP instead. Though I cannot see how this approach is useful I
have included it beause it was asked sometimes in the mailing list.
